What We Do

Craftsmanship, from curb to garden.

— 01

Interlock Driveways

Premium stone driveways engineered to hold their line for decades. Properly graded, properly edged, properly set — so your investment doesn't sink the first winter.

— 02

Flagstone & Patios

From black granite steps to natural flagstone entertaining spaces, we build patios that anchor your backyard and elevate how you live in it.

— 03

Landscape Design

Justin and Marisa are hands-on designers. Every project begins with a plan — material choices, proportions, flow — built around your home, not a template.

— 04

Custom Structures

Pergolas, retaining walls, pillars, and hardscape features built to the same standard as the stonework they complement. Details that make a space feel finished.

Our Story

Two people. One standard. No shortcuts.

Cornerstone is run by Justin and Marisa — a family operation, not a call center. Every project we take on gets our eyes on it, our hands on it, and our name attached to it. That's the whole business model.

We've been laying stone in Vaughan long enough to know that good work shows up in the details no one photographs: the base prep under the pavers, the drainage behind the wall, the edge that sits flush five winters later. We build like we're going to drive past it for the next twenty years — because we are.

They took the time to discuss the different stone options that would work best for us. Fair pricing and the quality of the work speaks for itself.
